I have completed B.E. Instrumentation & control in 2009. i have 3 year industrial job experience in chemical, I want to join M.E. in external. so, Plese say easiet way and good institute name.


i want formula for flow doing project in flow control using orifice . i know value of the flow level(Q) . upstream(p1) pressure, orifice diameter(Do) , pipe diameter(Di) and oil viscosity(Vi) how can i calculate downstream pressure


What is the difference between modbus,fieldbus & profibus



Anybody know how to create a ladder programme for power switch in TV remote without using counter... ie TV can be turn on and turn off using single push button switch... on pressing the switch first time TV turn on and hold the on state till i press the switch again, and after TV turn off.

What is Modbus communication


1. what is 3 point calibration & 5 point calibration? 2. If we use hart communicator to set the LRV & URV of a smart transmitter, did we calibrate the transmitter? why? 3. Make a complet list if meterials needed to properly connect a pressure gauge to a steam pipe using 1/2 inch stainless steel tubing. The gauge connections is 1/2 inch NPT-M and the steam pipe tap has a 1/2 inch female coupling, compression fittings are use. 4. What are the tools in loop checking? 5. What would the ISA symbol of a square root extractor look like? 6. What would you do to completely prepare for the configuration? 7. What safety measures must you undertake when doing configuration? 8. what are the two most commonly use programming languages used when we configure a PLC? 9. What would you do if you accidentally skipped a step in the configuration procedure? 10. How would you know if the configuration were sucessful? 11. Name at least 3 selections available when we configure the burnout protection of a controller?

We Have Two Field bus Pressure Transmitters of Different Sensor Range (I.E One is of Lower range and Another is of Higher Range).Is same Process Line. My Question is Can i provide Saturation Limit to my field Bus Transmitter as We can provide Saturation current limit to HART Instruments. As During Low Pressure Both Working OK ,But During High Pressure, transmitter with Lower sensor range Goes to Fault mode as Beyond its Sensor Limit it can Measure, So may I provide Saturation point Some where to Suppress This Fault during High Pressure.
